Description of detection logic

IsRegressionChecked: Marked as regression because the three check build points were 0.05 greater than the baseline.
IsImprovementBase: Marked as not an improvement because the compare was not 5% less than the baseline, or the value was too small.
IsRegressionBase: Marked as regression because the compare was 5% greater than the baseline, and the value was not too small.
IsRegressionChecked: Marked as regression because the three check build points were 0.05 greater than the baseline.
IsRegressionWindowed: Marked as regression because 8.809840346666666 > 6.8429103375.
IsChangePoint: Marked as a change because one of 6/6/2022 12:57:23 AM, 6/9/2022 4:58:43 AM falls between 5/31/2022 10:47:41 AM and 6/9/2022 4:58:43 AM.
IsRegressionStdDev: Marked as regression because -43.04850610024283 (T) = (0 -8515.495442396215) / Math.Sqrt((8604.243458239607 / (34)) + (22363.08013084935 / (12))) is less than -2.0153675744421933 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (34) + (12) - 2, .025) and -0.3030682739476988 = (6534.957233359824 - 8515.495442396215) / 6534.957233359824 is less than -0.05.
IsImprovementBase: Marked as not an improvement because the compare was not 5% less than the baseline, or the value was too small.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
